Solution Overview

Problem

Thermoform packaging machines face challenges in efficiently and consistently producing different package formats, especially with large containers filled with heavy content, due to difficulties in adjusting the cutting station for optimal separation and maintaining high-quality product production.

Innovation Solution

A thermoform packaging machine with a cutting station that features relocatable cutting units and a support system with adjustable support elements, allowing for flexible gap formation within a horizontal bearing plane to accommodate various package dimensions, ensuring precise and clean cuts while maintaining a stable support surface for different formats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cutting station is adjusted for different package formats by displacing cutting units along guide profiles, then the machine can produce various container sizes, but the adjustment process becomes complex and time-consuming

Engineering Contradiction:

Improvecapability to produce various container sizesVSAvoidcomplexity of adjusting the cutting station

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support is divided into multiple support elements that can be independently positioned and adjusted. Each support element can be individually relocated along the bearing plane to create gaps at different positions, allowing the cutting station to be adapted for different package formats without complex overall reconfiguration

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support elements are designed to be movable and repositionable along the bearing plane. This dynamic arrangement allows the support structure to adapt its configuration based on the required package format, enabling flexible adjustment of gap positions while maintaining a relatively simple overall device structure

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the cutting unit is adjusted for large container separation, then large packages can be optimally separated, but the support structure becomes insufficient for maintaining stability

Engineering Contradiction:

Improvecapability to separate large container formatsVSAvoidstability of support for heavy packaging contents

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Different regions of the bearing plane are provided with support elements having different properties or arrangements. The support elements can be selectively positioned to provide localized support where needed, allowing the structure to handle both large containers with heavy contents while maintaining stability through targeted support rather than uniform support across the entire surface

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The support elements are pre-positioned or pre-configured in optimal locations before the cutting operation. This preliminary arrangement ensures that when large containers with heavy contents are processed, the support structure is already optimized to provide stable support, preventing instability during the cutting operation

Inventive Principle:

Principle #10Preliminary action

3Area of stationary object

If the support surface area is increased to support large containers, then stability improves, but the gap formation for cutting operations becomes more difficult

Engineering Contradiction:

Improvesupport surface area for package bottomsVSAvoidflexibility in gap position for cutting

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The support surface is segmented into multiple discrete support elements rather than a continuous surface. This segmentation allows the support to cover a large bearing plane area while maintaining the flexibility to create gaps at different positions by simply relocating or removing individual support elements, thus resolving the conflict between large support area and gap formation flexibility

Inventive Principle:

Principle #1Segmentation

AI summary

A thermoform packaging machine comprising a forming station, a sealing station, and a cutting station for separating sealed packaging troughs from one another. The cutting station may comprise at least one cutting unit which is adapted to be positioned within the cutting station at different positions in the production direction. The cutting station may comprise a support that supports bottoms of the sealed packaging troughs conveyed into the cutting station for the purpose of separation from below. The support may comprise a plurality of support elements arranged in a horizontal bearing plane and which form a gap at a position in the support at which a cutting operation takes place according to the position of the cutting unit. The gap may be repositioned by moving the support elements to different positions to position the gap to accommodate a different position of the cutting unit within the cutting station.
